Why ASTM A573 structural hot-rolled steel is not easy to rust

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and ASTM A573 structural hot-rolled steel heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported ASTM A573 structural hot-rolled steel to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

SA516Gr.60 (HIC) steel plate is mainly used in the manufacture of equipment used in wet hydrogen sulfide environment, such as: liquefied petroleum gas desulfurization system, catalytic cracking stable absorption system, atmospheric and vacuum distillation tower condensation system, etc. The material ASTM A573 structural hot-rolled steel has the characteristics of high purity, low P, low S, good uniformity of structure and mechanical properties, resistance to hydrogen cracking and sulfide stress corrosion.

Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from ASTM A573 structural hot-rolled steel. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.

The thermal conductivity of NM360 wear-resistant plates is only 1/2 of that of carbon steel, ASTM A573 structural hot-rolled steel, and even in the high temperature stage of 900-1000℃, the thermal conductivity is lower than that of carbon steel at the same temperature. Therefore, the heating rate of the NM360 wear-resistant plate, especially in the low temperature stage, should be lower than that of carbon steel to avoid excessively steep internal temperature gradients and cracks.

How much is plate ASTM A573 structural hot-rolled steel per ton?
FOB Shanghai: 635$/ton
q345qd steel is steel for highway bridges, which is a thick steel plate specially used for erecting railway lines or road and highway bridges. It is required to have high compressive strength, ductility and bearing the load and impact of railway vehicles, as well as excellent fatigue relief, certain ultra-low temperature ductility and air corrosion resistance.
